2.0.4 Precautions
Components and electronic circuit boards can be damaged by
discharges of static electricity. Working on a system that is connected
to a power supply can be extremely dangerous. Follow the guidelines
below to avoid damage to GN70-B8236-HE or injury to yourself.

Ground yourself properly before removing the top cover of the
system. Unplug the power from the power supply and then
touch a safely grounded object to release static charge (i.e.
power supply case). If available, wear a grounded wrist strap.
Alternatively, discharge any static electricity by touching the
bare metal chassis of the unit case, or the bare metal body of
any other grounded appliance.

Avoid touching motherboard components, IC chips, connectors,
memory modules, and leads.

The motherboard is pre-installed in the system. When
removing the motherboard, always place it on a grounded
anti-static surface until you are ready to reinstall it.
 Hold electronic circuit boards by the edges only. Do not touch
the components on the board unless it is necessary to do so.
Do not flex or stress circuit boards.
 Leave all components inside the static-proof packaging that
they ship with until they are ready for installation.
 After replacing optional devices, make sure all screws, springs,
or other small parts are in place and are not left loose inside
the case. Metallic parts or metal flakes can cause electrical
shorts.
